Adjusting sweeps of wipers VAZ 2110 and not only

Reworking wiper relay (VAZ 2110)

According to the opinion of its owners, a disadvantage of a VAZ2110 car consists in insufficiently convenient work of wiper blades. In particular, the presence of 3 speeds in the work of wipers, as well as the process of washing the glass, the work of the brushes begins on the dry glass.

To solve this problem, you can use the services of Internet-shop or buy yourself on the auto-market alternative wiper relay (about 144r). Installation of purchased relay takes no more than one minute.

Advantages:

– Possibility to set frequency of wiper blows independently; – the first wave after windshield washing begins with sustained pause; – Number of wiper blows decreases (3 instead of 4);

There is also a way of self-tweaking wiper relay:

Adjusting the number of sweeps of the brushes on the car. The manufacturer initially provided 4 sweeps of the wiper blades after washing the glass, but after the completion of the second wave on the glass almost no water remains. As a result, the brushes begin to operate on a completely dry glass, and even with a nasty sound. But if you use the suggested trick, you can achieve a 2-fold decrease in the number of sweeps (2 instead of 4).

To begin with let’s consider and compare wiper relay of available (old) model

Then remove the factory diode resistance and install a resistor 40-70 kOhm. Adjusting the pause between sweeps frequency wipers.

What do you need to do for this?

Resistor 2,7 kOhm, which is on the second leg of the chip has output directly to the terminal “J” of the relay.

To get the initial delay of 1 second at the output you have to solder the old resistor and then solder the bought resistor of 600 ohm. If this is not done the relay will not work.

The next step: from this lead runs a striped yellow-green wire through the mounting block strip Shch4-10 to the contact “J” understeer switch.

To successfully adjust the pause between the frequency of wipers sweeps it is necessary to install a 22-47 kOhm variable resistor in the cut of this wire.

If you install 22 kOhm – the pause duration is 2-5 seconds, and if you install 47 kOhm – 2-38 seconds. There is also another option: it is possible to install a 47 kOhm variable resistor in the steering box casing near the steering column switch. To do this, you need to remove the wire on the shifter pad itself, which is on pin “J” and connect it through the single pad to the variable resistor. Then connect the other wire coming from the alternator to this place and put the lug on.

As for the purchased relays with pause adjustment (for example “Deca”), there are nuances (in particular to constantly use the shift lever to adjust). Among motorists there is an opinion that the homemade device is far superior to the purchase one.

Adjusting the speed of the brushes on the paddle lever.

First you need to buy a 47 kOhm variable resistor.

Such an option as connecting the contact to the “J” in the gap does not cause much difficulty. It is necessary to solder the wires (25 cm length) with the “dad” and “mom” terminals to the terminals of the resistor itself. It is recommended to remove the contact “J” from the switch block and connect it to the “dad” terminal from the resistor, and to insert the “mom” terminal from the resistor directly into the block. Then put a variable resistor (SP4-1 for 22 kOhm) on the end side of the handle.

The second way is to put the resistor on the thruster lever.

Conclusion: thanks to improvement of the wipers relay the perception of rainy weather does not become so overshadowing. Another nice benefit: the wiper settings have been added, which has a favorable effect on the quality of windshield cleaning in the rain. As a result of these positive changes, you can think about increasing the windshield wiping area, as well as increasing the windshield wiping level.

Causes of malfunction

Therefore, if the wiper blades are completely “frozen”, or only squeaky, the root cause should be looked for in the electric motor. Not forgetting that in addition to electrical problems, there may be malfunctions of a mechanical nature.

The most common ones are:

• When you turn on the windshield wiper, you can hear the motor working, but it itself only twitches or remains unmoved at all. First of all, you need to suspect that the nut securing the crank to the gear axle, unscrewed or loosened;
• If the windshield wipers work, but not synchronously, the lever may be the culprit. Most likely, the nut securing it has come loose. Before tightening it, you need to put the wipers in the right position.

If the electrical part is faulty, the symptoms will be as follows:

• The wipers work slowly, stop where they want, do not want to take the lower position. This may be the culprit limit switch. Its adjustment consists in bending the contacts. If this repair does not help, you need to replace the entire electric motor assembly, as it is sold only together with the gearbox;
• The intermittent mode is on, but the brushes work without stopping. Most likely, the relay has failed, it must be replaced. It is definitely a relay, if on VAZ, when the intermittent mode is on, no noise of wiper motor armature turning can be heard. But if replacement did not help, it is possible that the limit switch has oxidized or burnt contacts;
• You turn on any of the modes, and all you hear is the thermo-metal fuse clicking. The brushes are “standing” and you can’t hear the armature either. The first thing to check may be that the brushes are frozen, so they aren’t moving. By the way, this often blows the F5 fuse. Another possible cause is a burned out armature;
• The electric motor does not work, although both fuses are intact. You need to check all the contacts that the drive has as well as the motor. Perhaps the brushes hung up or the armature burned out.

Why are the wipers on the Lada Priora slow and how to speed them up

Many owners of Priora notice that over time the wipers began to work slowly. The speed has decreased several times and does not rise even when cleaning the wet windshield. Consider the main causes of slow wipers, as well as ways to solve this problem.

The main reason for the slow wipers of Priora is the lack of lubrication:

• In the wiper motor;
• On the pivots of the wiper blade.

Try to use grease that does not thicken at low temperatures. Trapezium with the motor is removed, as in VAZ 2110.

If lubrication of the motor and the trapezium did not help, it is recommended to use refinement. Priora windshield wiper circuit consists of a large number of connections and contacts, each of which creates additional resistance. As a result, the power of the motor falls, and wipers Priora work slowly. It is possible to eliminate this problem with the help of modification, which will minimize current losses.

1. A 5-pin connector, as on the wiper motor;
2. 5 pin relay with socket – 3 pieces;
3. wires 25mm 2 ;
4. round terminals.

Assemble and connect the construction according to the scheme. That is, the resulting block of three relays is installed in the gap connector wiper motor without interfering with the regular wiring. We recommend to pay special attention to the insulation of wires, and it is better to close the assembly in a box to exclude moisture and dirt.

As a result, the wiper blades will work faster than before. You can compare speed of wipers work on the video clip (1 – before improvement, 2 – after improvement):

Have you faced a problem when wipers started working slowly on your Priora? How did you managed to increase their speed? Remember, you can also find instructions on the site if wiper blades don’t work at all. Did you know that you can increase the windshield wiping area by installing oversized wiper blades?

With the onset of spring there are puddles and mud on the road, which make the wiper blades work more often than usual. The main problem faced by owners of VAZ cars during this period is the slow operation of the wipers. Consider a few ways to make your wiper blades work faster!

An alternative to .

When choosing wipers, it is not only their size that matters, but also the device and the manufacturer. For VAZ 2110 all years of manufacture for the wiper, driver or passenger side is one size – 20″ (wiper length 508 mm).

However, you should know that you can usually increase the size to 53 cm, but no more, otherwise the wipers will not cope with their task, and the drive can fail, because the leash is not designed for such a load. In addition, such wipers squeak during operation, can work jerkily.

If the size is chosen incorrectly, then the mechanism will fail sooner. In principle, many people use the “native” wipers VAZ, and are happy with them. But it is possible to refine the windshield wipers of other companies, often – better quality.

For example, for many people very attractive frameless brushes (especially – Boshev). They are compact, have a special mechanism of the driver. But at VAZ they are not particularly good-looking, since their attachment to the wiper blade of a conventional carcass is massive. Such wipers need refinement.

The VAZ 2112/2111 has a rear wiper, its size is 11″ (27.9 cm).

As a normal replacement, and refinement of the wipers begin with the disconnection of the minus terminal of the battery. Then you need to pull the wiper toward you, remove the brushes.

If there is a decorative cover, it should be removed. Unscrew the bolt, remove the old wiper. Be sure to compare the size of the new wiper with the old one. It will be better if the size of the wiper on VAZ 2110 is not more than 2 cm more than its predecessor. Install everything in reverse order.

Check whether the new wipers do not squeak, and how they obey the “commands” of the switch. They should work quickly at high motor speeds, and slowly at non-high and intermittent modes. Here, in fact, is the entire repair of the wipers VAZ.

The first step: diagnosis and troubleshooting of electrical problems

Every owner of the ten model probably noticed the clicks and noise coming from the left side of the motor gearbox when activating the wiper system. Therefore, at the initial stage of solving the question, why the VAZ 2110 wipers do not work, it is necessary to pay attention to the nature of the work of this unit.

The electric motor does not give any signs of performance – you need to inspect the fuse F5 in the assembly block, located on the left side under the hydrocorrector light beam of headlights. A faulty fuse serves primarily as an indicator of problems in the actuator feeding system.

Multimeter will help to identify the faulty section: it is necessary to “probe” the circuit in the resistance mode from the fuse to the electric actuator and to the control lever, and the switch itself. Multimeter induces zero: the section is serviceable, infinitely high value – an occasion to inspect the terminals and wires.

The fault can be eliminated by the following steps:

• strip/ crimp the terminals in the fuse box, pins of the paddle shifter and motor gearbox;
• Replace the wires;
• replace the lever on the steering column, which activates the wipers.

Relay K2, type 524.3747, located in the mounting block, is responsible for the operation of the wipers by paused cycles (I and II positions). The system does not work in intermittent mode – reason for a detailed inspection and replacement of the relay. In such circumstances, you should “blame” on the stalk switch.

Keep in mind! With defective relay, the windshield wipers work absolutely unprecedentedly in extreme third position of the right paddle switch.

However, the faulty relay does not always stop the unit in intermittent mode. The wipers can effectively perform their function in I and II positions, but the presence of defect in the relay will indicate the absence of pauses between brush strokes characteristic of these modes.

Along the way, finding out the other reasons why the wipers on VAZ 2110 in intermittent mode does not work with a pause, you should inspect the limit switch, located on the cover of the gear motor:

• oxidized layer should be removed;
• burned contacts should be cleaned;
• The contact blades, if necessary, should be bent.

Wiper repair

In practice, the repair of wipers on VAZ 2110 is not complicated at all, if you have at least elementary experience in working with the car and its electrical component.

Unscrew the fixing nut

To begin with, let’s understand how to remove the wipers on the VAZ 2110. The design provides for several fasteners, unscrewing which, you will easily remove the brushes themselves.

But with the disassembly of the wiper unit everything is a little more complicated. It is disassembled as follows.

1. Remove the dashboard.
2. On the left side, look for the relay, which is attached to the body. If it is broken, there is no point in repairing it. Just install a new relay.
3. Next, check the condition of the fuse that is responsible for operating the wiper actuator.
4. Disassemble the steering column, which allows you to examine the condition of the switch. If it has damaged insulation or other damage, replace the unit.
5. Unscrew the electric motor from the body and check it in operation. If the breakdown is not serious, you can repair it. If not, it’s better to replace it and the relay at once.
6. Check the actuator. It is not uncommon for a pulley to break on it, which causes the unit to have to be replaced with a new one.
7. Make sure the trapeze is in good working order. You may need to replace the wiper blade on VAZ 2110, if during the operation of the car deteriorated lubrication of the device, there got all kinds of debris, water. If the grease is not working properly, the plastic hinge bushings wear out, hence the backlash, and increases the resistance during operation of the device. The trapeze itself serves to transmit the force from the electric motor to the wiper blades.

Faults of mechanical origin

Mechanics Often the wipers on the car VAZ 2110 do not work because of the banal loosening of the nut that presses the brush holder to the shaft of the trapezium. Restore the functionality of the system can be instantly, adjusting the angle of the brush and pulling the lever nut. One of two things can tell you about a loose nut contributing to the torque transfer from the gearbox to the trapezium:

• The electric motor remains functional in all modes, but both brushes do not move;
• the brushes spontaneously stop working in an intermediate position.

However, the stopping of the brush holders in an arbitrary position can be caused by poor contact of the “limit switch” contacts with the gear of the motor or by oxidation/burn-out of the same contacts. And the brushes are not able to move even after the teeth of the gears, which do not have a long service life – because they are made of plastic, are cut off.

Bottom line

Wiper blades failure can occur due to quite trivial reasons:

• F5 fuse blown;
• Oxidized or burned terminals of connection pads;
• Wires are broken;
• Relay K5 524.3747 broke;
• The control pusher gave up its “long life”;
• the nut holding the crank to the gear pinion was loose;
• nuts fixing levers to the gear shafts loosened;
• the wipers are frozen to the glass.

Often the wipers on models of the VAZ 2110 family do not work due to complex level faults:

• oxidation/burnout, insufficient force of pressing the contacts of the limit switch, located on the gear cover;
• Brushes hang in the gear motor;
• Burned/soiled collector;
• Breakage in the armature winding;
• milling out of gear teeth in the reducer.
